| Outline of Final Research Achievements |
Paramagnetic complexes which show slow magnetic relaxation phenomena are known as single-molecule magnets (SMMs). In this work, we have proposed the mechanism of the slow relaxation of the magnetization for each lanthanide(III) ion, and synthesized several single-molecular magnets including Ce(III), Nd(III), Tb(III), Dy(III), Er(III), or Yb(III). Due to the characteristic 4f electrons, lanthanide(III) ions have large total angular momentum J and magnetic anisotropy. In the anisotropic ligand field, J ground state splits into Jz sub-states and in some cases, the Jz sub-states which direct along the z-axis were stabilized compared with other sub-state. This situation is known as Ising-type magnetic anisotropy. We have proposed how to design such an Ising-type anisotropy for each Ln(III) ion, and investigated the detail of slow magnetic relaxation features of the synthesized Ln(III) complexes.
